APPARATUS HAVING REDUCED NOISE AND METHOD OF USING THE APPARATUS FOR DETECTING IONIC MATERIALS |
摘要 |
An apparatus and method for detecting ionic materials includes a sensing electrode which contacts a liquid sample and detects a sensing voltage corresponding to a surface potential which is changed by a concentration of ionic materials in the liquid sample, a first switching transistor having a first terminal connected to the sensing electrode and a second terminal connected to a first node, a second switching transistor having a first terminal connected to a reset voltage and a second terminal connected to the first node, and a sensing transistor having a gate connected to the first node.
